Question

1. One-half of a number subtracted from
its thrice gives 2500. Find the number.​

Answer 1

Step-by-step explanation:

let the number be 'x'

1/2 of a number = x × 1/2 = x/2

thrice a number = 3x

3x - x/2 = 2500

( 6x - x )/2 = 2500

5x = 2500×2

5x = 5000

x = 5000/5

x = 1000

hence the number is 1000
